1. A coated substrate comprising a metal substrate and a polytriazole polymer on a surface of the metal substrate, the polytriazole polymer having a structure according to formula (I):

OG Complex Work Unit Chemistry
where:
R1 and R2 are independently selected from substituted phenyls according to formula (a) and substituted benzyls according to formula (b):

OG Complex Work Unit Chemistry
where, in formulas (a) and (b), X1, X2, X3, X4, and X5 are independently selected from hydrogen, bromo, fluoro, chloro, iodo, hydroxy, methyl, trifluoromethyl, dimethylamino, tert-butyl, carboxyl, triphenylmethyl, tris(4-fluorophenyl)methyl, tris(4-methylphenyl)methyl, (4-hydroxyphenyl)diphenylmethyl, and difluoromethoxy, provided at least one of X1, X2, X3, X4, or X5 is not hydrogen;
m and n represent monomer mole fractions in the polytriazole polymer;
m is from 0 to 1;
n is from 0 to 1;
m+n=1; and
the polytriazole polymer has a degree of polymerization from 50 to 400.
